Passengers on select JetBlue flights will be able to purchase food and drinks using their iPhone, USA Today reports. Customers will also reportedly be able to use the payment service to upgrade to any open premium seat once the flight has started.

Payments will be handled by airline employees using iPad minis with NFC-equipped cases. Over 3,500 of these devices have been issued to JetBlue staff. The cases will also accept regular credit cards, and will serve as a full replacement for the existing in-flight payment terminals.
